DAVID Ii. BARNES, OF CHICAGO, ILLINOIS.

TRUCK.`

Application filed March 19, 1896.

To a/ZZ whom t may concern:

Beit known that I, DAVID L. BARNES, a citizen of the United States, anda resident of Chicago, Illinois, have invented certain Improvements inTrucks, of which the following is a specification.

My invention relates particularly to the trucks of electric locomotives,but it will be understood that myimprovem entscan be used onrolling-stock in general Without departing from my invention.

The object of my invention is to stiften the truck so that it willwithstand the strains to which the truck of an electric locomotive issubjected.

In the accompanying drawings, Figure lis a plan View. Fig. 2 is a sideview. Fig. Sis a section 011 the line 3 3, Fig. l; and Fig. 4 is an endview.

A A are the side frames of the truck, each side frame, in the presentinstance, being composed of two plates a, a., secured together and todistance-pieces by rivets or bolts.

The pedestals a for the j ournal-boxes C are, in the present instance,made in the manner described and claimed in the application for pat-entfiled by George Westinghouse, J r., one side of each pedestal beingrigidly attached to the side frame of the truck, while the other side ofthe pedestal is movable, so that it can swing to allow for the readyremoval of the axle and its box from the truck.

On the axle C are the wheels c c.

Extending from one frame A to the other is a top plate D, made in onepiece, in the present instance, and reduced in width at the center, butextended at each end, these extensions being secured to the frames A byrivets or bolts.

In order to stien the .truck land make it perfectly rigid, I secure toeach edge of the plate D angle-plates D', curved at each end to conformto the shape of the top plate D. The upper iange d of each angle-platerests upon the top plate D, and the deep depending flange CZ' is securedto transverse plates E E, forming a box for the bolster F, which has anopen bottom, so that the bolsterand its springs can be removed from thebottom of the truck.-

Serial No. 583,936. (No model.)

The top plate D has a central opening and side openings for the passage,respectively, of the center plate e and the side bearingblocks e.

The swinging plate G carries the springs g g, one set at each end, andis suspended by links g from studs f, secured to the plates E. Thespringsggsupport the bolsterF. Openings are formed in the side frames Aopposite the springs, so that access may be had to them and to thebolster.

I have shown brake mechanism in Figs. 1 and 2, although this mechanismforms no part of my present invention, but is shown simply to illustratethe method of applying the brakes to this form of truck, and I have alsoshown in Fig. 2 the motors M M, which are hung to each axle andsuspended from the truck.

It will be seen by the above description that my invention is especiallyapplicable to electric-locomotive trucks where the space between thecenter box or beam of the truck and the axles has to be entirely freefor the reception of the motors, and by making the truck with simply asingle center beam composed of the two angle-plates curved at each endand the top plate and side plates I make a truck which is rigid in everyrespect and will readily support the weight without encroaching upon theroom reserved for the motors.

I claim as my invention- 1. The combination in a truck, of the sideframes, the transom, and angle-plates curved at each end, one flange ofeach angle-plate extending on top of the side plates and transom, theother flan ge extending down the side of the transom and side plates,substantially as described.

2. The combination of the side frames of a truck having pedestalstherein, a top plate extending from one side frame to the other narrowat the center and wide at each end where it is secured to Ithe sideframes, an

angle-plate on each edge of the said plates,A

one flange of the angle-plate being secured to the top plate and theother flange extending downward, substantially as described.`

3. The combination of the side frames, pedestals therein, a top plateextending from one frame to the other, vertical plates under name tothis specification in the presence of the top plate and angle-plates,one ange of tWo subscribing Witnesses. each angle-plate being secured tothe top plate and to the side frames, the otliei1 flange i DAVID L.BARNES. 5 being secured to the vertical plates and to Vitnesses:

the side frames, substantially as described. JAMES Gr. KEYS,

In testimony Wheieof I have signed my HENRY I-IOWSON.
